Metal Shark Debuts Prowler Autonomous Vessel and Frenzy Micro-USV
few sources. Frenzy will serve this demand, and putting Frenzy onboard Prowler makes perfect sense. Pairing an over-the-horizon capable USV with micro-USVs delivers a one-two punch capability, keeping the key asset safe while allowing the attritable drones to do their job, all while being watched from the sky.”Prowler and Frenzy will make their public debut April 8-10 at Sea-Air-Space 2024 in National Harbor, Md., before returning to Metal Shark’s Louisiana facilities for further testing and development.“We challenged the men and women of Metal Shark to dream big and to think outside

there are risks, and no matter how many challenges there are, Taiwan must take this step and allow the self-reliant national defence policy to grow and flourish on our land," Tsai said, standing in front of the ship, named the Narwhal. Taiwan's red flag, featuring a white sun against a blue sky, was wrapped around the submarine's bow.Tsai said the Narwhal will enter service in 2025, joining two existing submarines purchased from the Netherlands in the 1980s.China's defense ministry, responding to a question at a regular monthly press briefing about the submarine and how it could

He said his team scrambled to source chips from Taiwan to avoid delays by foreign vendors.A foreign supplier had also pull out at the last minute after the work with Taiwan was leaked to a Chinese
Marine Heatwaves Cause Chaos on the Seafloor
the powerful, deep and warm East Australian Current snakes westward towards the coast. As the current swings over the continental slope, it drags warm water over the shelf and close to the coast.In summer, Australia gets two very different types of heatwave in our oceans. The first occur when we get blue-sky weather. With few clouds, more heat from the sun gets into the oceans. They can also occur when there are weaker winds and less ocean cooling from evaporation. These heatwaves are confined to the surface and a few meters below.Then there’s the second, a very weird heatwave system that only appears
As the Clock Ticks on the Titan Sub, an Expert Explains What Safety Features a Submersible Should Have
to operate would mean no equipment is damaged and no passengers are prone to injury (or worse) while onboard. And protection of environment means the submersible would not have any significant impact on its surroundings, such as through pollution or disturbing the ecosystem.However, this is the blue-sky scenario. Deep-sea submersibles operate in a hostile environment, and things can go wrong.Pressure resistanceSubmersibles and submarines are shaped the way they are because spheres and cylinders are geometrically more resistant to crushing pressures.Instead of operating in a breathable atmosphere
Missing "Titanic" Submersible - Update

The founder and CEO of the vessel's U.S.-based operating company OceanGate is also on the submersible, according to media reports. "It is an amazingly beautiful wreck," Rush told Britain's Sky news of the Titanic earlier this year. "You can see inside, we dipped down and saw the grand staircase and saw some of the chandeliers still hanging."Based in Everett in Washington State, OceanGate says it uses next generation crewed submersibles and launch platforms to increase deep ocean
Happy to be Blue
in the March/April edition of Marine Technology Reporter“There’s something compelling about the color blue,” said Dr. Anya Waite, scientific director and CEO of the Ocean Frontier Institute (OFI) and associate and vice president research (ocean) at Dalhousie University. As the bright sky shone through her office window and the waters of Halifax Harbor glimmered through the tree line, blue seemed to be even more inspiring. OFI, based on Dalhousie’s campus, is an interdisciplinary research partnership between the university, Memorial University of Newfoundland (MUN) and the University

potential threats has been difficult.“One of the things we’re concerned about is swarms of drones,” Jackson said. “What if someone sends dozens or hundreds of drones against you? It is a very big challenge.”There are a few proven ways to counter unmanned aerial systems. Sky Wall uses a compressed air canister and a viewfinder to shoot a projectile that splits open and drops a net with a parachute attached to safely bring down a drone. Dronekiller uses electronics to jam a drone’s control signal to force it off target or to land. A pitfall of using electronic counter
